Jo-Mill Unit Mineral Rights — Borden County, Texas

Unit Overview

About the Jo-Mill Unit

The Jo-Mill Unit is one of the most active long-tenured oil units in west Texas Permian Basin. With 130 historic wells, an oldest spud date of 1955, and recent monthly production of 19,980 barrels of oil (February 2026), the unit demonstrates the long-tail production profile that characterizes mature unitized oil operations in the Permian Basin (eastern shelf).

Jo Mill Oil Company LLC is the long-tenured operator of the Jo-Mill Unit, an east Permian Basin / Borden County position with continuous production since 1955.

Jomill Field Geology & Production

The Jomill field sits in the Permian Basin (eastern shelf). The field has been producing oil since 1955 — a continuous production history spanning 71+ years. Modern operating consolidation under the Jo-Mill Unit framework has stabilized field-level production through pressure maintenance, waterflood, and (where applicable) CO2 enhanced oil recovery (EOR) operations.

Mineral Interest Profile

Mineral interests in the Jo-Mill Unit typically take one of these forms:

Producing royalty interest — your tract's contribution to the unit's monthly revenue, paid by the operator

Non-producing mineral interest — fee mineral ownership in a tract currently outside active producing zones

Overriding royalty interest (ORRI) — a royalty carved out of a working interest

Non-participating royalty interest (NPRI) — a royalty interest with no leasing or development rights

Many Jo-Mill Unit interests are inherited multiple generations deep, with original lease bonus paid in the 1930s-1960s era. Current Jo-Mill Unit mineral owners frequently include heirs spread across multiple states.

Valuation Considerations

Direct buyers value Jo-Mill Unit mineral interests using a discounted cash flow approach with these key inputs:

Decline rate — typically 3-8% annual on long-life unitized waterflood / EOR wells

Remaining reserve life — often 15-30+ years on actively-maintained units

Operator quality — well-maintained units (Jo Mill Oil Company LLC is established in west Texas Permian Basin) typically deliver predictable production

EOR upside — many Permian Basin (eastern shelf) units have CO2 EOR or other tertiary recovery upside not reflected in current production rates

Discount rate — typically 8-12% for stable unitized cash flows
